STITCHED BUTTONHOLE.

SPECIFICATION formingpart of Letters jPatent No. 735,433, dated August 4, 1903. Application'filed September 22, 1902. Serial No. 124,425. (No model.)

To all whom it may concern:

Be it known that I, EDWARD B. ALLEN, a citizen of the United States, residing at Elizabeth, in the county of Union and State of body of a buttonhole is or may be stitched around in the usual manner by'any purled. overseam, and the finished buttonhole is.

barred by stitches which are formed across the end of the buttonhole and overlaid by other barring-stitches radiating from the end of the buttonhole-slit, these radiating stitches forming a purl at their outer ends, and this purl may be so disposed as to lie in a straight or approximately straightline across the end of the buttonhole or may be disposed in the arc of a circle.

In the accompanying drawings, which are of a diagrammatic character, Figure 1 illus-'- completed operation. Fig. 5 is aview similar to Fig. 1, but with the p url of the radiating stitches disposed in the arc of a circle.

Referring to the drawings, a denotes an overedge-seam extendingabout the sides and eye of a buttonhole and the thread or threads of which are concatenated in any suitable or well known manner to form a continuous purl I) along the edges of the buttonhole-slit and about the eye of the buttonhole at the inner ends of the overseaming stitches. Formed across the end of the buttonhole-slit j are what may be termed crossing barringstitches c, which are overlaid and tied down by radiating barring-stitches (1, extending from the end of the buttonhole-slit as a center and radiating outward therefrom.

The improved butto'nhole preferably comprises two sets of crossing barring-stitches c and 0', the stitches 0 being formed at the commencement of the stitching operation before stitching the first side of the buttonhole, as denoted in Fig. 2, and the second set 0 being formed after'the last side of the buttonhole has been stitched, but before the radiating barringstitches d are formed, so that in either case the crossing barringstitches will be overlaid and tied or sewed down by the radiating barring-stitches.

In the diagrammatic drawings the crossing barring-stitches are represented by curved lines for clearer illustration; but as a matter of fact these stitches lie straight across the ends of the buttonholes. Also in the diagrammatic view, Fig. 4, the two sets of crossing barring-stitches are represented as being spread out, so as to occupy different positions, while in the improved buttonholes these two sets of stitches preferably lie in the same plane, one set on top of the other.

a purl e at their outer ends where the needle punctures and the thread or threads pass through the body of the goods, the seam thus formed making a very straight and peculiarly characteristic bar.

When the radiating barring-stitches are so disposed as to form a straight or approximately straight purl, as illustrated by Fig. l, the inner or slit needle or an overseaming-needle at its inner descents' stitches required for the completed buttonhole are formed in a piece of fabric j, which will preferably be cloth or leather.

The improved buttonhole is preferably made by a buttonhole-stitching mechanism such as is fully shown and described by my applications, Serial Nos. 24,679 and 113,808, filed, respectively, July 24:, 1900, and June 30, 1902, and in which the stitching mechanism travels and performs partial rotary movements and the work-clamp remains stationary, such machines forming overedge and barring stitches which in the concatenation of the threads are all of the same character in that both the overedge and the barring stitches are concatenated to form a purl, by which the inner ends of the .overseamingstitches and the outer ends of the radiating stitches are connected. The invention is not,

however, to be understood as being limited to any particular style of purl-buttonhole overseam or to any particular stitch-forming mechanism. Also, the invention may be embodied in straight buttonholes which are barred at both ends, in which case the buttonholes will of course be worked and barred on straight-buttonhole machines instead of the eye-buttonhole machines above referred to.

Having thus described my invention, I

claim and desire to secure by Letters Patent 1. A fabric having a stitched buttonhole comprising crossing barring-stitches lying across the end of the buttonhole-slit and radiating barring-stitches overlying the said crossing barring-stitches.

2. A fabric having a stitched buttonhole comprising crossing barring-stitches lying across the end of the buttonhole-slit and radiating barring stitches overlying the said crossing barring-stitches, the thread or threads of the said radiating barring-stitches being concatenated to form a purl at the outer ends of the said barring-stitches where the thread or threads pass through the material.

3. A fabric having a stitched buttonhole comprising two sets of crossing barringstitches lying across the end of the buttonhole-slit, combined with radiating barringstitches overlying the said crossing barringstitches.

4. A fabric having a stitched buttonhole comprising crossing barring-stitches lying across the end of the buttonhole-slit, com-- bined with radiating barring-stitches overlying the said crossing barring-stitches, the thread or threads of the said radiating barring-stitches being concatenated to form, at their outer ends, a purl which is disposed as a straight line, or approximately so, across the end of the buttonhole.

5. A fabric having a stitched buttonhole comprising two sets of crossing barringstitches lying across the end of the buttonhole-slit, combined with radiating barring stitches overlying the said crossing barringstitches, the thread or threads of the said radiating barring-stitches being concatenated to form, at their outer ends, a purl which is disposed as a straight line, or approximately so, across the end of the buttonhole.

6. A fabric having a stitched buttonhole comprising side stitches connected together at their inner ends bya continuous purl, and a bar comprising stitches lying across the side stitches and similarly connected together at their outer ends by a purl which is on the same side of the work as the purl at the inner ends of the side stitches.

7. A fabric having a stitched buttonhole comprising side stitches connected together at their inner ends by a continuous purl, and a bar comprising radiating stitches similarly connected together at their outer ends by a purl which is on the same side of the work as the purl at the inner ends of the side stitches.

In testimony whereof I affix my signature-
